Common Heavy Equipment & Truck Parts Definitions

Here are definitions for various common parts in construction, heavy trucks, agricultural machinery, and automobiles:

• Radiator (散热器): Located at the front of the engine compartment, this component cools the engine coolant to prevent overheating. Example: Caterpillar CAT 336 excavator Radiator (卡特彼勒CAT 336挖掘机散热器).

• Hydraulic Pump (液压泵): Typically found near the engine or in the hydraulic system, it converts mechanical power into hydraulic energy by pressurizing fluid. Example: Komatsu PC200-8 excavator Hydraulic Pump (小松PC200-8挖掘机液压泵).

• Turbocharger (涡轮增压器): Mounted on the engine's exhaust manifold, it uses exhaust gases to spin a turbine, compressing intake air for increased power. Example: Cummins ISX15 engine Turbocharger (康明斯ISX15发动机涡轮增压器).

• Brake Pad (刹车片): Part of the braking system, located within the brake caliper, the friction material that presses against the brake rotor to slow down a vehicle. Example: Freightliner Cascadia truck Brake Pad (福莱纳Cascadia卡车刹车片).

• Alternator (发电机): Usually mounted on the engine, belt-driven, this component generates electricity to charge the battery and power the vehicle's electrical systems. Example: John Deere 8R series tractor Alternator (约翰迪尔8R系列拖拉机发电机).

• Fuel Filter (燃油滤清器): Located in the fuel line before the fuel pump or injectors, it removes dirt, rust, and other contaminants from the fuel. Example: Volvo VNL truck Fuel Filter (沃尔沃VNL卡车燃油滤清器).

• Starter Motor (启动马达): An electric motor, typically mounted near the engine's flywheel, used to crank the engine to initiate the combustion process. Example: Kubota KX080 excavator Starter Motor (久保田KX080挖掘机启动马达).

• Piston (活塞): A cylindrical component that moves up and down inside the engine's cylinders, transferring force from combustion gases to the crankshaft. Example: Volvo D13 engine Piston (沃尔沃D13发动机活塞).

• Seal Kit (密封件修理包): A collection of various seals (O-rings, gaskets, etc.) used to repair leaks in components like hydraulic cylinders, pumps, or valves. Example: JCB 3CX backhoe loader Hydraulic Cylinder Seal Kit (JCB 3CX挖掘装载机液压缸密封件修理包).

• Injector (喷油器): A component in the fuel system that precisely sprays fuel into the engine's combustion chamber or intake manifold. Example: Volvo D13 engine Injector BEBE4D24002 (沃尔沃D13发动机喷油器 BEBE4D24002).
